To begin your search for expressive artwork, take a cue from your existing decor. Use metallic and wood wall art to your advantage and instill a certain vibe in viewers as their eyes explore your walls. Wood wall decor with metal accents blends these two materials for an appealing effect. Or, decide on a handcrafted metal wall sculpture, when you're after a more robust element. Framed art, on the other hand, makes for a traditional look.
